Abstract: In systems wherein signal compression is performed using matched filters or transforms, as in the case of radar, multiple extrapolations are used to resolve beyond the limits of diffraction. In one example (Figure 4), development of the method begins with a complex, uniformly weighted SAR or inverse SAR signal represented by a rectangle function. After performing an FFT (34), adaptive sidelobe reduction is carried out followed by an inverse weighting and truncation, after which the original signal is used to replace the center portion of the extrapolated signal (Figure 7). The signal is again transformed and sidelobe reduced, and inverse weighting and truncation are again performed, followed by the original data replacement step. The extrapolation procedure may be repeated end times, extrapolating each time by a factor K for a total extrapolation factor of K = k<n>.

Abstract: An improved dental floss is comprised of a plurality of low denier melt extruded polyethylene filaments having a tensile modulus of about 200 to about 2500 grams per denier and a coefficient of friction which is less than about 0.2. The low coefficient of friction and resistance to cutting of the fibers allows the floss to glide more easily between tight interproximal contact points, providing greater gentleness to the gum tissue, enamel, dentin and cementum than nylon. The individual filaments are preferably held together by a bonding material such as wax. The floss of the invention preferably incorporates at least one material selected from the group consisting of flavor, anti-caries, anti-tartar, and anti-plaque agents.

Abstract: Disclosed are non-periodic microstructured optical fibers that guide radiation by index guiding. By appropriate choice of core region and cladding region, the effective refractive index difference Δ between core region and cladding can be made large, typically greater than 5% or even 10 or 20%. Such high Δ results in small mode field diameter of the fundamental guided mode (typically < 2.5 µm), and consequently in high radiation intensity in the core region. Exemplarily, a fiber according to the invention has a solid silica core region (51) that is surrounded by an inner cladding region and an outer cladding region. The cladding regions have capillary voids (52, 53) extending in the axial fiber direction, with the voids (53) in the outer cladding region having a larger diameter than those (52) in the inner cladding region, such that the effective refractive index of the outer cladding region is greater than that of the inner cladding region. Non-periodic microstructured fiber potentially has many uses, e.g., as dispersion compensating fiber (with or without dispersion slope compensation), as amplifying fiber, as laser, as saturable absorber, for fiber gratings, and for non-linear elements. A method of making microstructured fiber is also disclosed.

Abstract: The connection between a toughened glass sheet (1) having a reamed hole and another glass sheet or metal structure comprises two parts. One part (7), which fits the hole conical surface (3), has a force perpendicular to the hole axis exerted on it. The other (14) is supported on the side (6) of the sheet opposite the reamed holed and supports the reaction force. The force is sufficient to establish on the glass sheet a system of minimum localised compression restraints at a distance from the hole edge greater than 1% of the hole maximum diameter. The metal connecting piece part fitting the reamed hole conical surface has a cone opening angle greater than that of the hole. An aluminium sleeve (23) is interposed between the connecting piece and the hole to avoid excessive local constraints.

Abstract: A sensor (1) is disclosed for the measurement of
moisture in a flow of material, especially loose material
such as meal material, grains, granulates and similar
materials which are to be pressed to form feed pills in
presses, in connection with pre-processing such as the
extrusion of feedstuffs, and for the measurement of a
finished product, regardless of whether this is pelleted or
extruded. The sensor (1) comprises a tube piece (2) of an
electrically conductive material with circular cross-section,
and an elongated pole (3) which is of circular
cross-section and is disposed with its longitudinal axis
(4) concentrically and electrically insulated in the tube
piece (2), and which consists of an electrically conductive
material. 
     When the moist material flows between the inside surface of
the tube piece (2) and the outer side of the pole (3), the
sensor (1) works as a condenser for the capacitive
detection of the moistness,
which can be determined on the basis of the detection. 
     There is hereby achieved a very accurate measurement of the
content of moisture in the material, even though the
material flows in a pulsating manner.

IPC: G10L19/12
Filed: 1997-01-31
Abstract: In a CELP coder a comparison between a target signal and a plurality of synthetic signals is made. The synthetic signal is derived by filtering a plurality of excitation sequences by a synthesis filter having parameters derived from the target signal. The excitation signal which results in a minimum error between the target signal and the synthetic signal is selected. The search for the best excitation signal requires a substantial computational complexity. To reduce the complexity a preselection of a small number of excitation sequences is made by selecting a small number of excitation sequences resembling the most a backward filtered target signal. With this small number of excitation sequences a full complexity search is made. Due to the reduced number of excitation sequences involved in the final selection the required computational complexity is reduced.
